Patch to allow Pulseaudio device selection

SDL2 does only support the default device for pulseaudio. Device detection does not work and adding an other device than the default, causes the default audio device to be selected.

I created a patch to fix that behaviour (tested on amd64 Mint Linux 17 and Pandaboard/arm with Ubuntu.)
Also it adds device detection and implicitely adds the capability for multiple devices at the same time (did not work because only default device). Only for pulseaudio.

Would like to second this enhancement request.  Just made a bugzilla account to request addition of multiple device selection for Pulse, ALSA, or both, and saw this has already been requested.

This would be very useful for audio software that needs to target a specific device, eg in radio/music contexts.

Marking a large number of bugs with the "triage-2.0.4" keyword at once. Sorry
if you got a lot of email from this. This is to help me sort through some bugs
in regards to a 2.0.4 release. We may or may not fix this bug for 2.0.4,
though!

Static Pulseaudio

Found out that the old patch breaks the build with static pulseaudio, this is fixed in this update.
